COMBINED BOTTLE AND STOPPER.

SPECIFICATION forming part of Letters Patent No. 722,053, dated March 3,1903.

Application filed December 8, 1902. Serial No. 134,322. (No model.)

T0 on whom it may concern:

Be it known that I, WILLIAM STENDER, a citizen of the United States, anda resident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in aCombined Bottle and Stopper; and I do hereby declare that the followingis a full, clear, and exact description thereof.

My invention has for its object to insure gas-tight fit of aluminiumstoppers in bottles containing carbonated beverages, especially beer;and it consists in what is hereinafter particularly set forth withreference to the accompanying drawings and subsequently claimed.

Figure 1 of the drawings is a sectional View of a bottle-neck and analuminium stopper seated therein with a gasket to constitute a gas tightstopper for the same; Fig. 2, a similar view of the bottle-neck andstopper before the latter is set gas-tight in the former; and Fig. 3, aplan view of said stopper as it appears in the second figure, theproportions in all the views being considerably greater than actualsize.

Referring by letter to the drawings, A indicates the neck portion of abottle contracted in the throat to form a horizontal annular shoulder b,and which is also indented immediately above the shoulder to formtherewith an annular groove 0 0f gradually-increasing diameter in adownward direction.

An aluminium stopper B for the bottle is normally in the shape of a cuphaving an upper downwardly-flaring outer flange d, as is best shown inFig. 2, and a gasket 0 of any suitable packing material is arranged toface the inner side of said flange. It is also preferable, as hereinshown, to indent the lower portion of the stopper-wall to provide aninwardly-projecting lug 6 under which to catch the point of anextracting-tool.

The stopper as made for the trade in the shape above specified is placedin the bottleneck to have the gasket-lined flange thereof rest on thehorizontal inner shoulder 19 of said neck, after which it is subjectedto pressure and forced farther down, whereby its flange is laid parallelto said shoulder over the interposed gasket, said flange and gasketbeing extended into the lower portion of the bottle-neck groove 0, asshown in Fig. 1. The stopper is now gas-tight in the bottle-neck andcannot be removed without the aid of an extracting-tooth.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Abottle having the neck portion thereof contracted in the throat toform a horizontal annular shoulder and also indented immediately abovethe shoulder to therewith form an annular groove of gradually-increasingdiameter in a' downward direction, together with an aluminium stopperhaving normally the form of a cup provided with an upper outerdownwardly-flaring gasket-lined flange, but which is pressed down in thebottle-neck to extend its flange and the gasket therewith parallel tosaid' shoulder and within said groove.

2. A bottle having the neck portion thereof contracted in the throat toform a horizontal annular shoulder and also indented immediately abovethe shoulder to therewith form an annular groove of gradually-increasingdiameter in a downward direction, together with an aluminiumstopperhaving normally the form of a cup provided with an inner wall-lug and anupper our-er downwardly-flaring gasket-lined flange, but which ispressed down in the bottle-neck to extend its flange and the gaskettherewith paralleik WILLIAM STENDER.
